The JP & JD Series are high precision CT complied with Electronic Watt-Hour Meter (0.1 / 0.2 / 0.5 class). Those are designed for power plant, distribution and industrial instruments. Characteristical are excellent properties of phase angle and linearity error in the low current. This series are closer to zero on the temperature dependence. The JP & JD series for electronic watt-hour meter are complied with IEC 62053-22, ANSIC12.xx and EN 50470-3. We also offer indirect connected CT (industrial meter) and direct connected CT to the main (residential meter).
